` Application flcdJnly 13, 1853. (No model.) I

To @ZZ whom, t may concern:

Be it known that I, J AMES lWIoR'roN, of Norwich, in the county of NewLondon and State of Connecticut, have invented a new and usefulImprovement in Governors for Vater- 4Wheels; and I hereby declare thefollowingto be a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, forming part of thisspecicat'o 1.

This invention has reference to' an improvement 'in the construction ofmachines for governing the water-supply to water-wheels; and it consistsin the peculiar and novel application of a friction band and brake, b'ymeans of which the power is applied in one or the opposite direction tooperate the gate, as will be more fully set forth hereinafter.

VFigure lis a view of` my improved automatic water-wheel governor. Fig.2 is an end view of the same. Fig. 3 is a sectional view of one ofthedriving-gears, the driving-head, and the friction-disk by which the gearis connected with the gate-operating shaft. Fig. 4 is a View partly 4insection, showing the connection of the friction-band with the gear-lwheel and friction-disk. Fig. 5'is a view of the friction-disk, showingthe brake-shoe and its connection.

In the drawings, A is the driving-pulley, by which the governor isdriven from any constantly-moving shaft, so that as long as-the'water-wheel is in motion the governor will also be in-motion. Thedriving-pulley Avis secured to the horizontal shaft a, on which twopinions, a', are fixed, one of which gears into and drives the gear B,and the other, through the intermediate pinion, a, 'drives the gear Binthe opposite direction. The gears B andv B are driven constantly inopposite directions. Theyare loosely mounted on the hub of the E and Eare friction-disks mountedloose on the shaftD. The gear B is connectedwith the friction-disk E by the brake-band d, one

end of which is connected with the gear-wheel B or B, and the other withthe friction-'disk E or E', the direction of the motion being such thatthe brake-band d is kept open until resistance is encountered by thefriction-disk E, so that one end of the band is held when the constantlydriven gear-wheel B draws the brake-baud tightly on the periphery ofvthe driving-head, and thus communicates the motion to the shaft D.It-will thus be seen that when resistance is appliedto the friction-diskE theshaft D will turn in one direction, and when applied -to thefriction-disk E it will turn in the opposite direction, and as theshaft-D is provided with the beveled pinion D",which Y gears into thebeveled gear D, secured to the gate-operating shaft, the gate will bemoved in one or the opposite direction when the resistance is applied toonel or the other of the friction-disks E or E. This alternateresistance is applied throughthe speed-governor G, which is the ordinarycentrifugal ball-governor driven by intermediate gears from thedrivinglshaft a, so that any acceleration of the speed of H by means ofthe lever h, the weight of therod and force ofthe governor beingcounterbalanced by the weights h', so that the operation of the governorcan be adj usted with great nicety. Y

vTo make the governor act with precision and prevent the brake-shoesHHfrom retaining their positions after the gate has been regulated, thebeveled gear I is secured to the shaft D, on the end opposite to thebeveled pinion D. The beveled gear I gears into the gear t' on the shaftk, on which the worm l is placed, which gears into the worm-gearm,secured to the shaft n, on which the brake-shoes H H and levers h 7L aresecured. The wormgear m is provided with the slots o o, in which studsprojecting from a plate. secured to the shaft n pass, so that theworm-gear may be turned nearly one-half of arevolution before the studsbring up against the ends of the slots and operate the shaft a, so as torelease the IOO brake-shoe fronifcontact with the frictiondisk. As theworm-gear turns very slowly, sufficient time is allowed for thebrakeshoes to be released; and it is only when such release does nottake place, and to prevent the gate from being moved too far, that thisparticular' safety appliance is used.

p is a stop secured to the shaft n, and gis a camshaped disk, a portionofwhich is cutaway.

ris a hand-lever for turning the disk so as to allow thestop to bearagainst the saine or pass by the saine, and thereby prevent or permitthe turning of the shaft n and the operating of the brake-shoes.

By the use of the brake-bandd and the brakeshoes H the changes in thedirection of the governor are made easygvithout sudden stops, so thatthe strain is brought on the gears and other parts of the governorgradnall y and without shock, thereby insuring durability and freedomfrom repairs.

Having thus described 1nyinvcntion,I clai n1 as new and desire to secureby Letters Patent- 1. Ina water-wheel governor, the combina tion, withthe. inain driving-shaft a and pinions aa, of the gears B and B',inonntedloose' on the driving-heads C (l, the friction-disks E and E',and the strap-brakes Il, constructed to bc operated through thegovernor', and the brake-shoes Hto regulate the gate, as described.

2. The combination, with the main drivingshaft and its pinions, of thegears B B, the drivi iig-heads C, friction-disks E and E', stra-ps d (l,the governor G, rod g', and shoes II II, constructed to move the shaft Dand regulate the water-supply, as described.

3. In a water-wheel governor,.thecombination, with the shaft D, of thedriving-heads C C, the gears loosely mounted on the drivingheads, thedisks E E, and band-brakes l d, constructed to connect and disconnectthe gears, as described.

4. The combination, with the gears B B', driving-heads C C, disks E E',and band-brakes d d, and the brake-shoes H H, niountedon the shaft n andcontrolled by the governor, ol'

the beveled gear I, pinion l,worml, and woringear mf, provided with theslots o o, constructed to release the brake-shoes, as described.

In witness whereof I have hereunto set 1nyhand.
